Kinetics of taurine depletion and repletion in plasma, serum, whole blood and skeletal muscle in cats.

abstract：:A thioalkylation procedure, which uses molecular sieves to promote the reaction, was exploited to provide peptides with useful functional groups (lipidic moieties), naturally occurring on proteins as post-translational modifications. The procedure was further implemented to synthesize tailor-made lipidated peptides, i...

abstract：:The chemical modification of protein by nonenzymatic browning or Maillard reactions increases with age and in disease. Maillard products are formed by reactions of both carbohydrate- and lipid-derived intermediates with proteins, leading to formation of advanced glycation and lipoxidation end-products (AGE/ALEs). Thes...
